hib-config.xml
的配置是这样的

这段配置数据源的配置代码 是配置Oracle 的
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName"
value="oracle.jabc.driver.OracleDriver">
</property>
<property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:springmvc"></property>
<property name="username" value="springmvc"></property>
<property name="password" value="springmvc"></property>
</bean>

org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'dataSource' defined in class path resource [spring-config.xml]: Could not resolve placeholder 'connection.driver_class' in string value [${connection.driver_class}]
但是报错是这样的
表示无法理解 我表示我没有 配置文件叫做 spring-config.xml
